I see. If that is the case, then the language of the description is rather confusing.May want to consider altering it. Here is the relevant part:

Shadow Noxomancers can, manipulate shadows around them(In a variety of ways...none of which include making a physical object out of the shadows), enter the Nox to travel distances in half the time in the mortal realm, and summon opposites from the Nox. The only known way for Shadow Noxomancers to enter the Nox is through shadows, not darkness. So, if there's a hint of light, a Shadow Noxomancer can dart through the shadow cast and travel through the Nox(EX: In a battle, they dissapear into their own shadow to reappear behind their opponent.)

When it comes to manipulating shadows, Shadow Noxomancer's can't make physical objects out of them, but they can make themselves near invisible in it, or cover a wide area in shadows, or distract with shadows being things they should not. The possibilities are only limited to the Shadow Noxomancer's imagination.
